基于星载高光谱数据的遥感数据预处理

遥感影像的预处理是遥感数据应用的基础,预处理结果的好坏将影响图像的质量及后续的研究。研究利用高光谱数据对穿越香格里拉县中部一景EO-1 Hyperion数据进行预处理。预处理分别进行envi补丁下数据波组合、未定标和水汽影响波段去除、绝对辐射值转换、大气校正等处理,结果表明:图像质量提高,减少了数据运算量,为应用研究奠定了基础。。

Remote Sensing Date Preprocessing Based on Spaceborne Hyperspectral Data

Remote sensing image preprocessing is the basis of remote sensing data application,pretreatment results will affect image quality and follow-up studies.This paper studied on preprocessing Shangri-La's central King EO-1 Hyperion data by using hyperspectral data.Preprocessing included ENVI data wave portfolio,outstanding in patches separately and moisture influence band removal,absolute value,atmospheric correction and so on.The results showed that image quality was improved,the amount of data for subsequent data was reduced.It built a good foundation for the research of function and utilization.
